5:30 p.m., Woods (R): The Brooklyn folk-rockers are now seven albums deep into a career that mines the spookiest corners of traditional music.

XXXX 5:15 p.m., Angel Olsen (B): A glistening voice and stripped-down songs bring the drama at its most intimate.

4:35 p.m., Mac DeMarco (G): This Canadian singer-songwriter plays it slapdash and low-fi on record, but can get boisterous and lewd on stage. R. Kelly may not be the only singer getting explicit in Union Park this weekend.

XXXX 4:15 p.m., Trash Talk (B): The interracial California hardcore band put out an album last year on the Odd Future hip-hop collective’s label.

8:30 p.m., Belle & Sebastian (G): The once-wispy Scottish folk-rockers haven’t exactly turned into Slayer, but they’ve toughened up their sound and amped up the dance pulse on recent releases while maintaining their allegiance to melody.

7:45 p.m., Andy Stott (B): The British DJ brought a new luster to his dark electronic music last year on “Luxury Problems.”

5:45 p.m., Ryan Hemsworth (B): The former Canadian singer-songwriter has transitioned into adventurous hip-hop and electronic production, remixing and composing.

XXXX 5:15 p.m., Swans (R): Michael Gira’s ensemble was at the forefront of the most punishing brand of no-wave out of New York in the ‘80s; in its second incarnation, Swans delivers sweeping, orchestral beauty and chilling melancholy.

XXXX 4:45 p.m., Metz (B): No one will sweat and grind more for your listening pleasure this weekend; this Toronto art-punk trio is not to be missed.

XXXX 4:15 p.m., Savages (G): The U.K. quartet’s debut, “Silence Yourself,” is among the year’s best. The live show is even better, with incisive lyrics and lacerating songs.

8:45 p.m., TNGHT (B): The duo’s blend of electronic music and hip-hop has earned the endorsement of Kanye West.

XXXX 8:30 p.m., R. Kelly (G): The dominant R&B singer-songwriter-producer-performer of the last 20 years, Kelly is a controversial headlining choice because of a 2008 trial in which he was acquitted on child-pornography charges.

XXXX 2:30 p.m., Killer Mike (G): The Atlanta MC is finally being recognized as one of hip-hop’s most distinctive voices, thanks to “R.A.P. Music” (2012) and “Run the Jewels” (2013). Let’s hope he and his recent collaborator El-P find a way to join forces on stage.
